It's done on a whim: a man acts like a woman because he wants to; it's desire-based.
He deals with none of the biological burdens of being a woman: periods, risk of pregnancy, giving birth, risk of death and injury from pregnancy and birth.
He retains the muscularity of a man and can easily beat women in sports. 💪🏻
When people do this with race, we call it blackface.
I recently had the pain of dealing with a bike shop owner who now identifies as a woman. From my few interactions with him and some of the odd things he said I can say with a straight face that I am completely disgusted with the fetish they're pushing on everyone. That's what this is. A 55+ year old man with kids decides that he's now a woman is not body dysphoria, it's people hopping on a bandwagon.
Time for a new bike shop!
